LDRS Radius-II Series PRO
Wet-Rated Slim Wafer · 4″ / 6″ / 8″ · CCT-on-J-Box
The slim wafer that doesn’t stop at six inches. Three sizes — 4″, 6″, 8″ — on one 0.38″ ultra-slim platform: 90+ CRI, edge-lit PMMA, wet-rated end to end. Set the CCT once at the Plug-n-Play J-Box and you never climb back up. Matte Black and Copper trim plates, a T-Grid kit for drop ceilings, and EM15 / JBM emergency drivers all ship from the same catalog — one spec, one BOM, one project drawer.

Dimensions
(For the selected size)Highlights & Features
Seven upgrades the rest of the slim-wafer category sells separately.
3 sizes (incl. rare 8″) · constNT CRCU-EM24/JBM EMB · contrLS by CS sensors · Universal NCP rough-in · 5-CCT on the J-Box.
The 3-Component Install System
The disk is the easy part. The J-Box is the upgrade.
Three components ship together: wafer disk (spring-clip cutout install) · Plug-n-Play J-Box (remote · 5-CCT dip switch on the face) · optional T-Grid Installation Kit (4″ / 6″ · 2×2 or 2×4 lay-in, no tile cutting). One catalog, one install kit, one BOM line.
The Radius-II wafer disk itself — a 0.38″ ultra-slim stamped-aluminum heat-sink with edge-lit PMMA optic, frosted polycarbonate diffuser face, and spring-loaded retention clips at 6N–8N elasticity force. Drops into a standard cutout (Ø4 21/64″ for 4″ · Ø6 19/64″ for 6″ · Ø8 5/64″ for 8″), pops in with the clips, and you're done — no can required, no separate housing, no backbox to wrestle. A plenum-rated quick-connector cable links the wafer to the remote J-Box (Component 2). Click Plug-n-Play J-Box next to see the install upgrade.

115° edge-lit PMMA beam. Pick a size and CCT.
Radius-II ships a single 115° edge-lit beam from the PMMA optic — one beam shape, ten lumen cells across 4″ + 6″ (5 CCTs each). Pick the size and CCT below; peak candela, total lumens, and the IES filename update with the selection. Every plot below is rendered from the real LM-79 IES file for that cell — tested by EVERFINE on a GO-2000B goniophotometer (2024-02 / 2024-06). 8″ (LDRS818) photometrics not yet published — flagged for engineering follow-up.

Nine companions. One catalog. One PO.
Nine drop-in companions for the LDRS Radius-II — controls, egress, and rough-in — on the same PO as the wafer. Two contrLS by CS Bluetooth-Mesh PIR sensors (8 FT in-unit · 40 FT high-bay) · one constNT Mid-Power J-Box Quick-Install emergency driver (24W · 90 min · UL 924) · two New Construction Plates (LCDL-SE/NCP · with or without integrated J-Box) for 4″–10″ rough-in · four datasheet-listed dimmers (Leviton + Lutron). ETL / JA8 / Damp pedigree throughout.

Documentation & Resources
Everything specifiers, contractors, and property managers need to spec, install, and certify Radius-II — the data sheet (live), the IES photometric bundle (live), and the live submittal generator. Sell Sheet, Installation Guide, and ENERGY STAR Certificate are pending engineering registration — the install topology is shared with Radius-I (LDRS-Radius-I_Installation.pdf on disk).
The full multi-fMILY collection.
Radius-II is one luminaire in a thirteen-product collection engineered specifically for multi-family residential — in-unit living, corridors, baths & wet locations, common amenity zones, and drop-grid commercial spaces. Same factory, same CS controls platform, same JA8 / Title-24 / Wet Location pedigree across every tier. If Radius-II isn't the right fit for a given zone, one of these is.
For the whole property.
Radius-II handles the slim-wafer recessed install — corridors, common areas, in-unit ceilings, drop-grid commercial spaces, and any zone where the spec calls for a flush 0.38″ ultra-slim wafer with detachable trim accessories. These cross-line fixtures handle everything else on the property — parking lot, walkways, garage, leasing office — same CS controls platform, same factory, same warranty. Specify them together for a single-source multi-family package.
Built for turn-over speed.
Hundreds of thousands ship from five US warehouses — 2-3 day QS lead means a unit refurb between tenants doesn't wait on lighting. Layouts back in 48 hours, quotes and rebate matches reply same business day. 24-pack contractor cartons standard.
Stack the California rebates.
Radius-II is JA8 / Title-24 compliant and ENERGY STAR certified — the hooks that unlock CalEnergyWise, PG&E / SCE / SDG&E utility rebates, and HUD multi-family programs. Typical offset on a property-wide retrofit: 25-50% of fixture cost (Radius-II is PRO tier — larger rebate envelope than eCrescent ECO; ENERGY STAR + JA8 paths apply at every IOU). We'll match your APN and pull the paperwork. Note: Radius-II is not DLC-listed; commercial rebate ladders that require DLC don't apply — for DLC paths, see Eclipse-II.
